摘　　要：以AUDI盘式制动器为研究对象 ,在JF 132型汽车制动器试验台上进行防抱制动器的模拟试验 ,在获得大量实验数据的基础上 ,运用曲线拟合和优化技术 ,建立一种可以模拟制动压力 力矩动态响应非线性滞环特性的经验模型 ,在相同制动压力输入的前提下 ,比较模型的理论计算结果与试验测量结果 ,分析所建模型的有效性和精确性。In this paper,simulation test of anti-lock AUDI disc brakes is performed by using JF-132 automobile brake tester.Considering the hysteresis phenomenon between brake pressure and brake torque,a nonlinear hysteresis model is developed on the basis of test data,whicn can simulate dynamic characteristics of the actual pressure-torque response.The model parameters that reflect nonlinear characteristics are obtained by least square curve fitting in order to minimizing the model error.The torque output from the model is compared with that from anti-lock brake test for the same pressure input,and the results are analyzed to examine the effectiveness and preciseness of the model developed.
